Iodine Deficiency Disorders in Children in East Khasi Hills District of Meghalaya, India.

OBJECTIVE: To assess the prevalence of iodine deficiency disorders among school-going children in Meghalaya. METHODS: Multi-stage 30 cluster sampling with probability proportionate to size (PPS) method was used. Children (age 6-12years) were examined clinically for goiter. Urinary iodine excretion (UIE) was performed by spectrophotometric method. Iodine content in the salt was analyzed using iodized salt test kits. RESULTS: A total of 195 (7.22%) out of 2700 children had goiter on examination. Goitre prevalence was significantly associated with wasting (P<0.05) and stunting (P <0.001). The median (IQR) UIE level was 150 (108.05 - 189.37) µg/dL. Nineteen (9.74%) children had severe iodine deficiency (UIE<20µg/L). Iodine content was above the recommended level of 15 ppm in 95.9% salt samples. A positive correlation was observed between household salt consumption and UIE levels (r=0.25; P<0.001). CONCLUSIONS: Iodine deficiency disorder is a public health problem in Meghalaya, which needs to be addressed.

Nutritional status and personal hygiene practices of primary school children: A cross-sectional study from Meghalaya, India.

BACKGROUND: Poor nutritional status in primary school children can lead to several health problems such as easy susceptibility to common childhood diseases. Personal hygiene status is an important predictor of nutritional status and morbidity in children as water- and sanitation-related diseases are the leading causes of early morbidity and mortality in children. The present study was conducted to assess the nutritional status as well as personal hygiene practices of primary school going children. METHOD: The present study was a cross-sectional study conducted in selected urban and rural areas of Shillong in children 6-12 years of age. Two schools each from the rural and urban area were selected using simple random sampling. The total sample size calculated was 510. Height, weight, and BMI were taken for all the children following the standard procedures. WHO growth standards were used for grading of nutritional status. A questionnaire with scores was used for grading of personal hygiene status. RESULTS: The overall prevalence of underweight in the children of 6-9 years was 74 (18.7%) and that of stunting was 68 (17.2%). The overall prevalence of thinness and stunting in children aged 10-12 was 38 (19.1%) and 46 (23.2%). The prevalence of nutritional deficiency syndromes was 192 (32.4%). Regarding the personal hygiene status, it was observed that 65 (11%) had very good personal hygiene, 292 (49.3%) were labeled as good, 200 (33.8%) were average, and 35 (5.9%) had poor personal hygiene. CONCLUSION: The primary school going children in Shillong had poor nutritional status but the majority of them had good personal hygiene practices. Mother's educational status played an important role in determining the nutritional and personal hygiene status of the children.

Tobacco: Consumption pattern and risk factors in selected areas of Shillong, Meghalaya.

BACKGROUND: The percentage of adults above 15 years who consume tobacco in Meghalaya as per the Global Adult Tobacco survey is 55.2%. AIM: In the context of the high burden of tobacco use in Meghalaya, this study aims to study the consumption pattern and the sociodemographic correlates of tobacco use in the urban slums of Shillong, Meghalaya. MATERIALS AND METHODS: This study is a cross-sectional study conducted in adults over 15 years of age. Data collection was done by personal interview using a pretested questionnaire during house-to-house visit after taking informed verbal consent. RESULTS: A total of 400 people were included in this study. Most of the study population belonged to the age group 15-24 years (120, 30%). The majority of the study population (322, 80.5%) were aware of the health hazards of tobacco consumption. Most of the population (287, 71.75%) were tobacco consumers with 265 (76.4%) of them having co-addictions. In the study, 35% consumed smokeless forms, 30% were into smoking, and 35% consumed both forms. A significant association was observed between the status of tobacco consumption and knowledge of second-hand smoke harm (P = 0.019) as well as knowledge of any law regulating tobacco consumption (P = 0.026). CONCLUSION: It was observed that despite having a basic knowledge of the ill effects of tobacco, its consumption is still widely prevalent in the region. There is a need for stringent laws regarding tobacco consumption and proper measures should be taken to enforce these laws.

Loss to follow up during diagnosis of presumptive pulmonary tuberculosis at a tertiary care hospital.

BACKGROUND: Sputum microscopy is still used for diagnosis of drug-sensitive pulmonary tuberculosis (TB). Revised National Tuberculosis Control Program (TB programs) aims to rapidly diagnose and treat all cases of TB. The aim of this study is to find the proportion of loss to follow up during diagnosis of pulmonary TB after the patient reached hospital (was handed over sputum cups for sputum collection) from DOTS center after referral from respective outpatient department (OPD) at a tertiary care hospital. METHODOLOGY: Record-based data from designated microscopic center at a tertiary care hospital were collected regarding the number of patients who had been given sputum cup container for sputum collection for diagnosis of pulmonary TB referred from different OPDs from January to December 2015. RESULTS: A total of 1518 presumptive patient for pulmonary TB had visited DOTS center after referral from different OPDs in the hospital for sputum examination during the above period. The loss to follow-up during diagnosis among presumptive pulmonary TB patient was 461 (30.04%), which was higher among those below 15 years of age. At this rate of loss to follow up of presumptive TB patient to submit sputum for diagnosis, it was estimated to be about 46 smear-positive pulmonary TB cases per year which will be missed out for diagnosis during the above period (considering sputum positivity rate is 10% in the hospital). The mean gap between sputum referral to submission of two sputum samples was 2.73 days (95% confidence interval 2.52-2.84) among those of submitted sputum for diagnosis. CONCLUSION: Approximately one-third of presumptive patient for pulmonary TB had loss to follow-up for diagnosis of TB even after consulting a doctor at a tertiary care hospital. There is a need to address this gap in diagnosis of pulmonary TB in this region.

Syphilis infection among female sex workers in Nagaland, Northeast India: analysing their vulnerability to the infection.

This paper describes the sex work characteristics and factors associated with syphilis among female sex workers (FSWs) in Dimapur district of high HIV prevalence Indian state, Nagaland. The study recruited 426 FSWs in 2006 using respondent-driven sampling. The prevalence of syphilis was 21.1% and HIV prevalence was 11.7%. Approximately half were under 25 years of age. Clients were solicited mainly in public places (32.7%), while hotels/lodges/rented rooms were the most common places of entertainment (57.2%). Condom use during the last sex was 36.5% with occasional and 27% with regular clients. Being married, being widowed/divorced/separated, being illiterate or having a history of drug use increased the likelihood of syphilis infection. Entertaining clients in bars/booze joints decreased the probability of syphilis. FSWs who moved between soliciting in public places or bars/booze joints and then entertaining in hotels/lodges/rented rooms had a higher vulnerability to syphilis. In summary, we found that the vulnerability to syphilis among mostly young FSWs in Dimapur varied according to their sex work characteristics, marital and educational status and drug use habits. They may be more vulnerable to HIV and sexually transmitted infections (HIV/STIs) due to the low rate of condom use. The findings have direct implications for HIV/STI prevention programmes in Northeast India.

Nutritional status of adolescents among tea garden workers.

OBJECTIVE: The study was conducted to evaluate growth and nutritional status using weight and height based indicators among tea garden adolescent boys and girls of Assam aged between 10-18 years. METHODS: A cross sectional study was carried out in the tea gardens of Dibrugarh district of Assam through house to house visit. Households were selected through two stage sampling design to reach out the adolescents. Height and weight were measured using standard procedures. Body mass index (BMI) was computed from height and weight. Height-for-age below 3rd percentile values of NCHS reference was classified as stunting. BMI-for-age below 5th percentile values of WHO recommended reference was classified as thinness. RESULTS: Total numbers of 605 adolescents (boys-291, girls-314) participated in the study. School enrollment rate was only 59.2%. Prevalence of stunting was 47.4% and 51.9% among boys and girls respectively relative to NCHS reference, which reduced to almost 30% while Indian reference data was used. Prevalence of thinness was higher among boys (59.5%) than girls (41.3%) counterparts. Mean BMI among girls was higher at all ages than boys. CONCLUSION: Almost half of the adolescents were stunted and most of them were thin. Problem of overweight was seen in less than 0.5% of adolescents. Factors typical to underdeveloped society seems to contribute to the moderate to high prevalence of undernutrition among adolescents working in tea gardens.

Tobacco and alcohol use among the youth of the agricultural tea industry in Assam, India.

A cross-sectional study was conducted to assess tobacco use (both smoking and non-smoked tobacco) and alcohol use among tea garden youths of Assam, India during the period 2002-2003. A total of 650 tea plantation youth age 15-24 years (255 males, 395 females) from eight randomly selected tea plantations, Dibrugarh District, Assam, were interviewed to collect information on alcohol and tobacco use using a pre-designed, pre-tested questionnaire. Nearly 59% of the respondents had no formal education. Fifty-eight percent of the youth used at least one substance and 27.4% were concurrent users of both alcohol and tobacco. The smoking rate was only 2.2% (4.7% in males, 0.5% in females). However, 52.5% of the study population used non-smoked tobacco (56.9% males, 49.6% females). The prevalence of alcohol consumption was 32.2% (43.9% males, 24.6% females). A higher rate of alcohol and tobacco use was found among the respondents who had no formal education or were school dropouts. A higher rate of alcohol and tobacco use were seen among respondents in whom both parents were illiterate. Working as a manual worker in the tea industry is significantly associated (p<0.01) with higher rates of alcohol and tobacco use. We recommend a vigorous campaign against tobacco and alcohol use among tea plantation youth to reduce the health risks associated with the use of these two substances.

Health problems and disability of elderly individuals in two population groups from same geographical location.

OBJECTIVE: To compare morbidity, disability (ADL-IADL disability) along with behavioral and biological correlates of diseases and disability of two elderly population groups (tea garden workers and urban dwellers) living in same geographical location. METHODS: Two hundred and ninety three and 230 elderly from urban setting and tea garden respectively aged > 60 years were included in the study. Subjects were physical examined and activity of daily living instrumental activity of daily living (ADL-IADL) was assessed. Diagnosis of diseases was made on the basis of clinical evaluation, diagnosis and/or treatment of diseases done earlier elsewhere, available investigation reports, and electrocardiography. Hypertension was defined according to JNC-VI classification. BMI (weight/height2) was calculated. Logistic regression analysis was performed to see the impact of important background characteristics on non-communicable diseases (NCD) and disability. RESULTS: Hypertension (urban--68% and tea garden--81.4%), musculoskeletal diseases (urban--62.5% and tea garden--67.5%), COPD and other respiratory problems (urban--30.4% and tea garden--32.2%), cataract (urban 40.3% and tea garden--33%), gastro-intestinal problems (urban--13% and tea garden--6.5%) were more commonly observed health problems among community dwellings elderly across both the groups. However in contrast to urban group, serious NCDs like Ischaemic Heart Disease (IHD), diabetes were yet to emerge as health problems among tea garden dwellers. Infectious morbidities, undernutrition and disability (ADL-IADL disability) were more pronounced among tea garden dwellers. Utilization of health service by tea garden elderly was very low in comparison to the urban elderly. Both tea garden men and women had very high rates of risk factors like use of non-smoked tobacco and consumption of alcohol. On the other hand, smoking and obesity was more common in urban group. Most morbidities and disabilities were associated with identifiable risk factors, such as obesity, tobacco (smoked and non-smoked) and alcohol consumption. Educational status was also found to be an important determinant of diseases and disability of elderly population. Age showed a J-shaped relationship with disability and morbidity. Sex difference in health status was also detected. CONCLUSION: This study highlights the physical dimension of health problems of elderly individuals. Social circumstances and health risk behaviours play important role in the variation of health and functional status between the two groups. Life-style modification is warranted to prevent onset of chronic diseases. To improve quality of life, rectification of poor health status through affordable health service for disease screening and better management of illness, nutritional improvement and greater health awareness are necessary particularly among low socio-economic group. Low-cost intervention like cataract surgery could make a difference in the quality of life of elderly Indian.

Study of health problems and nutritional status of tea garden population of Assam.

BACKGROUND: Assam is the highest tea producer state in the country. There is scarcity of reliable information on health and nutritional status among tea garden population of Assam to enable initiating public health response to their health needs. AIMS: To describe health problems and nutritional status among tea garden population of Assam. SETTINGS AND DESIGN: Community-based cross-sectional survey in eight randomly selected tea gardens of Dibrugarh district of Assam. MATERIALS AND METHODS: Socio-demographic and behavioral characteristics of participants were recorded. Health problems and nutritional status were assessed through medical examination, evaluation of medical records, anthropometry and laboratory investigations. STATISTICAL ANALYSIS: Percentage prevalence; Chi-square test was applied wherever applicable. RESULTS: Out of 4,016 participants, 1,863 were male and 2,153 were female. They were mostly illiterate and nearly 52.9% (1,197 of 2,264) of adults were manual workers in the garden. Alcohol and oral tobacco use were common. Prevalence of underweight among children was 59.9% (357 of 596) and thinness among adults was 69.9% (1,213 of 1,735). Anemia was widespread. Worm infection (65.4%, 217 of 332); skin problems; respiratory infections, including tuberculosis; filariasis were present in a significant way. Children suffered more in various diseases. Major noncommunicable diseases like hypertension, stroke were emerging in the community and were associated with modifiable risk factors like alcohol and tobacco use. CONCLUSION: Health status of the population can be ameliorated through better hygienic practices, environmental sanitation, creating health awareness, nutritional intervention and overall improvement of socioeconomic conditions of the population.

Correlates of alcohol consumption and tobacco use among tea industry workers of Assam.

An epidemiological study on alcohol and tobacco (smoking and nonsmoked tobacco) use was carried out in tea garden population of Assam, one of the largest agroindustries of India. A total sample of 2,264 individuals (male, 1,033; female, 1,231) aged 15 years and older was interviewed in 2002-2003 to collect information about alcohol and tobacco use using a predesigned and pretested questionnaire. Age-adjusted prevalence of alcohol consumption was 59.2% (male, 69.3%; female, 54%). Smoking was more common among males (13.2%) than females (2%). However, use of nonsmoked tobacco was almost as popular among female (71.9%) as among males (75.3%). More than half of the respondents (54.7%) were multiple users of alcohol and tobacco. Prevalence of alcohol consumption, nonsmoked tobacco use, and smoking among the young age group (15-24 years) was 32.2%, 52.5%, and 2.2%, respectively. Prevalence of smoking increased with age, and more than a quarter of males above 54 years were smokers. Similar age trends in the prevalence of alcohol and nonsmoked tobacco was not observed. Sociodemographic correlates, like education, occupation, and marital status, emerged as important predictors of substance uses irrespective of sex. Association of income with substance use was weak in this study, perhaps due to homogeneity of income level. Users of alcohol and tobacco were mostly illiterate, manual workers, and widows/widowers. However, smokers were more common among sedentary worker. Not withstanding the limitations of the study, the findings of the study are useful for planning interventional strategy to control alcohol and tobacco use for better health outcome.

Cure and reinfection patterns of geohelminthic infections after treatment in communities inhabiting the tropical rainforest of Assam, India.

Mass de-worming targeted at socio-economically poor communities can be considered as an option for communities living in the tropical forests of Assam who do not have access to safe drinking water and proper sanitation, and consequently have a higher risk of suffering from geohelminthic infection and associated morbidity. A random sample of 265 subjects was included in this study (134 males and 131 females). The chemotherapeutic regimen followed was a single dose of albendazole 400 mg. Stools samples were collected in 10% formol-saline for detection of infection before treatment. Post-treatment stool samples were collected 10 to 14 days after treatment to determine the cure rate. Stool samples were again collected 3 to 6 months post-treatment to study the rate of reinfection. Multiple logistic regression was used to find possible associations between age, sex and treatment failure. The chi-square test was used wherever appropriate. The cure rates for Ascaris lumbricoides, Trichuris trichiura and hookworms were 70.8%, 68.7% and 93.0%, respectively. Logistic regression revealed that age was associated with treatment failure in A. lumbricoides infection. Re-infection rates after 3 months of successful treatment were 19.6% for A. lumbricoides, 30.9% for T. trichiura and 11.3% for hookworms. Six months post-treatment, the prevalence of re-infection was highest with T. trichiura (43.6%); followed by A. lumbricoides (35.3%). The rate of reinfection with hookworms was lower (11.3%) six months post-treatment. The rates of re-infection with A. lumbricoides and T. trichiura was higher in children below 15 years of age, compared with adults. Hookworm reinfection was higher in the adult age group (15 to 39 years). The rates of new infection in previously uninfected subjects were lower compared with the rates for re-infection.
